Peripheral Ossifying Fibroma is a non–neoplastic enlargement of the gingiva with randomly distributed calcifications, immature bone and osteoid. It is found exclusively on the gingiva and does not arise in other oral mucosal location. Clinically, it resembles a peripheral fibroma, but histopathologic analysis always reveals immature bone and osteoid within the lesion. Its incidence is 0.5% in the older age group. We report a rare case of Peripheral Ossifying Fibroma in a 70- year old female. Clinical, radiographic and histopathological features along with etiopathogenesis and differential diagnosis are also discussed.
